Type-locality: — Antigua. 



Type: — M. C. Z. 12,084, a very young and therefore misleading specimen. 

 Dr. D. W. Griswold. 



Distribution: — Antigua. 



Diagnosis: — Medium sized, with rather large keeled, imbricate dorsals of 

 which twelve or thirteen equal the distance from tip of snout to centre of eye ; a 

 middorsal zone of scales of decidedly lesser size; only three large supralabials 

 and the anterior pair of these bordered by only five large scales in the basal 

 loreal row. 



Description of type: — Snout rather short but acute, the distance from tip of 

 snout to eye being about equal to distance of ej^e from ear-opening, and more 

 than twice the diameter of the eye, which is rather small; rostral rather large 

 with a median cleft behind; nostril between rostral, first supralabial, one or two 

 small postnasals and a decidedly enlarged supranasal which is separated from its 

 fellow on the opposite side by a single scale, slightly smaller than one of the 

 supranasals ; these three scales border the rostral posteriorly ; three large supra- 

 labials to below the centre of the eye ; above the centre of the eye the usual spine- 

 like scale is present; top of head covered with tiny granules increasing in size 

 upon the neck; back covered with larger keeled slightly imbricating scales and 

 with a very narrow ill-defined median dorsal zone of scales of much reduced size, 

 these characters evident in adult; in the yoimg type 13 scales or in the adults 9 

 scales, counting in a straight line on the middorsal region are equal to the distance 

 from the tip of the snout to the middle of the eye ; scales of chest and belly round, 

 smooth, and slightly imbricating, scales of throat granular, of limbs granular 

 in young type, swollen, keeled, but nonimbricating, in adults; scales of tail in 

 whorls, squarish, flat, not imbricating in young type, slightly imbricating in 

 adult, a subcaudal series of enlarged scales, mental large, as large as rostral, 

 followed by a very large, a medium sized and a very small infralabial; two small 

 squarish postmentals slightly enlarged. 



Colour: — Rich mahogany-brown, the head lighter than the body; very 

 narrow pure white cross-bands arranged as follows, one on nape, one just ante- 

 rior to and another just behind fore limbs, two across midbody, one just before
